IPC: H01M10/39
Filed: 1990-08-09
Abstract: PURPOSE:To produce a beta-alumina electrolyte raw material composed of nearly single phase with easy low-temperature calcination process by adding acetic acid to a mixed solution containing alkoxides of Al and Na at a specific ratio and hydrolyzing with a methanol-diluted water to obtain a gel. CONSTITUTION:A mixed solution of an aluminum alkoxide and a sodium alkoxide is prepared at an Al:Na atomic ratio of (6-10):1. The mixed solution is mixed with acetic acid and then hydrolyzed in one stage by adding methanol- diluted water in an amount not less than the amount necessary for hydrolysis, preferably about <=4 times the necessary amount. The gel produced by this process is aged, dried at about 70 deg.C and calcined at a low temperature (about <=1200 deg.C, preferably about 1000-1100 deg.C). A single-phase beta-alumina electrolyte raw material composed of fine particles having diameter of about <=0.5mum can be produced by this process.

Filed: 1996-08-08
Abstract: PROBLEM TO BE SOLVED: To obtain calcium aluminate high in curing rate, by exothermic oxidation between aluminum residual ash and a calcareous stock in a kiln in an oxidative atmosphere while keeping the system at high temperatures. SOLUTION: First, aluminum residual ash containing about >=20wt.% of metallic aluminum and 40-70wt.% of Al2 O3 and a calcareous stock such as limestone powder >=80wt.% of which is passable through a 200-mesh sieve are mixed together under agitation, and the mixture is charged into a rotary kiln, subsequently, the kiln is forcedly fed with air followed by heating while rotating the kiln to initiate the reaction. The exothermic oxidation of metallic aluminum then proceeds and the system reaches a temperature of as high as about 1,600-1,800 deg.C. By the reaction between the Al2 O3 and CaO, a high-viscosity reaction product in a semi-molten state is formed.  Thereafter, the system is air-cooled to bring the in-kiln temperature to about 1.000 deg.C and the reaction product is taken out as dumpling-like lumps each about 2-100mm in size followed by forced cooling an then crushing the product, thus obtaining the objective calcium aluminate fine granules composed of >=70wt.% of 12CaO.7Al2 O3 ingredient and the rest of Al2 O3 , MgO, SiO2 and others.

Filed: 1998-07-24
Abstract: PROBLEM TO BE SOLVED: To provide a drain water collecting pipe capable of remarkably enhancing draining ability by permitting the enlargement of essential swirl vanes while securing a predetermined inner diameter of the drain water collecting pipe. SOLUTION: Originally an inner wall 51a of a pipe with the radius reduced to a tapered pipe shape toward the bottom is changed in shape to a pipe inner wall 1a having a roundness swelled externally. Thus, it becomes possible to extend a root portion 12a of a turning vane 12 outwardly in radial direction and also a projected end portion 12b inwardly in radial direction thereby permitting the enlargement of the swirl vane. Thus, a great amount of drain water current is created and accordingly the drainage capacity can be enhanced.
